Subject: [PATCH v1 07/22] drm/panel: jdi-lt070me05000: Backlight update
Date: Sun,  2 Aug 2020 13:06:21 +0200
Message-ID: <20200802110636.1018743-8-sam@ravnborg.org> (raw)
In-Reply-To: <20200802110636.1018743-1-sam@ravnborg.org>

Update backlight to use macro for initialization and the
backlight_get_brightness() operation to simply the update operation.

Moved init of backlight device so it comes after drm_panel_init().
This is the order that is required by drm_panel.
